Seriously, the free tier in every app allows for enough opportunities to match with someone. Whether that happens is really a matter of your looks (or well, the photos you're using).
Getting lots of matches is useless when you're looking for a handful of great matches. For that you need a great matching mechanism with thousands of parameters - what OkCupid used to have before Match Group destroyed it.
Just so you're aware, Match owns OkCupid now, as well as Tinder, Hinge, Plenty of Fish and a bunch of other smaller dating sites. I don't think they've all been ruined as much as Match yet, but it's probably only a matter of time.
And one of them (Match?) apparently hsd a decency algorithm that matched people on things like religion and politics, but was disabled after being bought out.
